Paper presented at the Annual Technical Meeting, June 7–9, 1998
Paper Number: PETSOC-98-35
.... The flow unit models were found to have a common feature in that each flow unit can be represented by a straight line with a unique slope and intercept. The methodology used in developing the models is presented. Also, a step-by-step example calculations is provided to show how the developed models can...

... these goals. The proposed flow unit models are based on current shale models appearing in the literature. These flow unit models introduce unique parameters for reservoir characterization of shaly formations. These parameters include the slope of a straight line (that defines the flow unit) and the stress...

... that the transition period should yield a straight line with a slope equal to % the slope of the early and late straight lines. Her examples showing the % slopes gave values of storativity ratios approximately equal to 0.37, 0.26, and 0.48. Serra et al. (8) reached the same conclusion with the use of a stratum model...

.... Applications of this well testing model were demonstrated by simulating the transient pressure behaviour of a falloff test conducted at a steam or air injection well The results suggested that, depending on the size of the swept zone and the severity of wellbore storage effect, the first semilog straight line...

.... This procedure consists of p/z plot of the "flowing" pressure (asopposed to the "shut-in average" reservoir ressure) versus cumulativeproduction. A straight line can be drawn through the data and then, a parallelline, drawn through the initial reservoir pressure, gives the initialgas-in-place, ariations...

.... In practice it seems that most tests are analyzed with T,-tly +t 27' presumably because it generatbo a straighter line on the Horner plot. Unfortunately, the slope of this straight line can be very misleading. This is not to say that this slope is "wrong" since Horner slope in and of itself...

This investigation shows that them is neither early-time straight line nor spherical flow period. What may appear to be a straight line on these plots is merely the result...

This technique showed that plotting change in pressure versus time on a log-log scale for late time data yields a straight line. Soliman2...

... Abstract If the duration of the flow period preceding a buildup test is not sufficiently long an apparent semi-log straight line may still be seen both on a type curve match and a Horner plot. The analysis of this semi-log straight line results in the wrong value of permeability...
